GOAL-EMPTIER.

v Specification of Letters Patent. Patented} Jan. 16, 1917.

Application filed. May29, 1912. Serial No. 700,496.

invention resides in the novel construction,

combination and arrangement of parts of a coal-car emptying apparatus as herein- ,after fully described in the specification,

summed up in the claims, and illustrated in the drawing.

Briefly stated, the invention comprehends a structure in which automatically-operating, vertically-descendant spears or push-- bars operate in conjunction with hammers knocking on the side of the car to be emptied, to loosen and remove the coal within the car. More specifically stated, the invention comprehends a novel mechanism, common to said push-bars and said hammers, for simultaneously operating them, which is a great advantage over actuating the hammers and the push-bars independently, a". e., by mech-. anisms not inter-related.

The invention is graphically illustrated in the accompanying drawing, in which like reference-characters denote corresponding parts throughout the specification.

In this drawing: Figure 1 is an end view of a coalcar of the dumping species, equipped with my invention; Fig. 2 is aside elevatlon thereof; Fig. 3 is a partial transverse section on the line 3-3, Fig. 2; Fig.

4 is a top plan view; and Fig. 5 1s .a fragmentary, collective, detail view of the main shaft, with its crank and connections with the hammers. Referring, now, in detail to the d H designates a frame or box, in this instance rectangular and preferably constructed of steel, arranged to be disposed on top of the dump-car 2.

H is a longitudinally-extendlng, rotatable shaft A, carrying rigidly a gear-wheel B and rawing Mounted in bearings aon top of the frame loose and fixed pulleys b, b, which maybe connected, in the usual manner, with a suitable prime-mover, or source of power (not shown).

-Meshing with the gear-wheel B is a pinion b fast on the end of a longitudinallyextending, rotatable shaft amounted in bearings in the frame H, and carrying, at the opposite-end, a fly-wheel 0. The shaft 0 also carries cranks D, to which are pivoted links -cl, pivoted to transversely-extending, horizontal, reciprocable rods 6, pro]ecting through bearings inthe sides of the frame H, and carrying, at their outer ends, longitudinally-extending, horizontal shafts E, E,

guided'in brackets F, F, F, F, carried by' the sides of the frame H, exteriorly thereof.

Hammers G are carried at the lower ends of depending hammer-rods g, pivoted, at their upper ends, as at g, to the sides of the I box H, near the top thereof. The hammerrods 9' are provided with longitudinally-extending slots 9 in which work pins f passing through the free ends of yokes or forks pErojecting from and carried by the shafts Vertically-disposed spears or push-bars K project vertically through the frame or box H, and are provided, along one edge, with rack is, with which mesh operating-members, in this instance teeth It (although, as is obvious, cog-wheels or pinions may be used instead), carried by the shaft 0.

In operation, when it is desired to empty a car of coal, the box or frame H may be disposed or lowered upon the top of the dump-car 2 by any suitable mechanism (forming no part of my invention). The power is then connected upwith the fixed pulley b, which revolves the latter and, with it, the shaft A and the gear wheel B. The gear-wheel, meshing with the pinion 1), drives the latter, which, in turn, drives the shaft 0. The revolution of the shaft 0, through the medium of the cranks D and the links d, reciprocates the rods e back and forth, which movement of said rods, by reason of their connection with the hammerrods g, rocks the latter back and forth on their pivots g, ringin the hammers forcibly into contact with t e sides of the car 2, thereby knocking the coal from the sides of the car. Simultaneously, the teeth h are revolved, which, by reason of their engagement with the racks k, force the spears or push-bars K downward through the coal in the car 2, thereby pushing the coal out of the bottom of the car.

From the above description, taken in connection-with the drawing, the many advantages of my invention will be apparent, especially to those skilled in the art to which the invention appertains.

I am aware that many modifications in detail may be made; but all such changes as come within the scope of the appended claims constitute no departure from the spirit of the invention and fall within the purview thereof.

Having thus fully described my invention,

what I claim as new and desire tosecure by Letters Patent-of the United States is:

1. In a coal emptier, upright push-bars adapted to be driven through the coal in a car to force the coal therefrom, hammers adapted to be knocked against the side of the car, and means, common to both the push-bars and the hammers, for simultane ously actuating them.

' 2. In a coal emptier, upright push-bars adapted to be driven through the coal in a car to force the coal therefrom, hammers adapted to be knocked against the side of the car, and power-driven means, common to both the push-bars and the hammers, for simultaneously actuating them.

3. In a coal emptier, upright push-bars adapted to be driven through the 'coal in a car to force the coal therefrom, hammers, carried by hammer-rods, adapted to be knocked against the side of the car, and means, common to both the push-bars and the hammers, for simultaneously actuating them, said means including: a rotatable shaft, reciprocable rods, and mechanism connecting sa1d shaft and rods, whereby movement of the former actuates the latter.

4:. In a coal emptier, upright push-bars adapted to be driven through the coal in a car to force the coal therefrom, hammers, carried by hammer-rods, adapted to be knocked against the side of the car, and means, common to both the push-bars and the hammers, for simultaneously actuating them, said means including: a rotatable shaft, cranks carried by said shaft, reciprocable rods, and links connecting said shaft and rods.

5. In a coal-em'ptier, a box, upright pushbars projecting through said box, hammers adapted to beknocked against the sides of the car, hammer-rods carrying said hammers and pivoted to said box, and means, common to both the push-bars and the hammers, for actuating them simultaneously. b 6. In a 'coal-emptier, a box, upright pushars adapted to be knocked against the sides of the car, hammer-rods carrying said ham-v mers and pivoted to said box and means, commonto the push-bars and the hammers, for simultaneously actuating them, said means including: a shaft, members carried by said shaft and engaging said push-bars to force the latter downwaxrd upon rotation of said shaft, and mechanism intermediate said shaft and said hammer-rods to actuate the latter upon movement of the former.
